Glyoxal

Glyoxal, also called ethanedial or ethane-1,2-dial, is the smallest dialdehyde, a yellow crystalline solid with formula OHC–CHO. It cross-links textiles and paper and forms in the atmosphere from isoprene oxidation.

Glyoxalase I

GLO1 (glyoxalase I, GLYI) is a human chromosome 6p21.2 gene encoding the zinc-dependent, rate-limiting enzyme of the glyoxalase system, which detoxifies methylglyoxal to S-lactoylglutathione; dysregulation links to diabetes, cancer, and schizophrenia.

Glyoxylate carboligase

Glyoxylate carboligase (EC 4.1.1.47, tartronate-semialdehyde synthase), E. coli gcl-encoded TPP and Mg2+ enzyme, homotetramer, condenses two glyoxylates into tartronate semialdehyde plus CO2 in glycolate degradation.

Glyoxylate cycle

Glyoxylate cycle (glyoxylate shunt): modified TCA cycle bypassing CO2-evolving steps, converting two acetyl-CoA to malate. Found in plants, bacteria, fungi; absent in vertebrates; key to seed oil-to-sugar conversion and M. tuberculosis persistence.

Glyoxylic acid

Glyoxylic acid, also known as oxoacetic acid, is the simplest α-keto acid, a two-carbon molecule with both aldehyde and carboxylic acid groups, used in the pharmaceutical, food, and perfume industries.

Glyph

Glyph: the visual form representing one or more characters in typography and fonts. Distinct from character, code point, and grapheme; Unicode encodes characters, not glyphs, with fonts mapping codes to glyphs.

Glyphipterigidae

Glyphipterigidae (sedge moths), family Stainton 1854 of Yponomeutoidea moths; about 535 species, wingspans 4.5–30 mm, diurnal adults with metallic forewing markings, larvae boring in sedges, rushes, and grasses.

Glyphosate

Glyphosate (N-phosphonomethyl glycine), sold as Roundup, is the world's most used broad-spectrum herbicide, inhibiting plant EPSPS; IARC calls it a probable carcinogen while EPA, EFSA, and ECHA disagree.

Glypican

Glypicans (GPC1-GPC6) are GPI-anchored heparan sulfate proteoglycans with a conserved ~63 kDa cysteine-rich core that modulate growth factor and morphogen signaling; GPC3 mutations cause Simpson-Golabi-Behmel syndrome.

Glyptemys insculpta

Glyptemys insculpta, the wood turtle (tortue des bois), a sculptured-shell semiaquatic turtle of eastern North America; IUCN Endangered, Threatened in Canada, threatened by roads, agriculture, and collection.

Glyptocephalus cynoglossus

Glyptocephalus cynoglossus, witch flounder or grey sole, is a deep-water right-eyed flatfish of the North Atlantic (Labrador to North Carolina and Europe), slow-growing and long-lived, IUCN Vulnerable, with several stocks under moratorium or rebuilding.

Glyptodon

Glyptodon: extinct Pleistocene South American glyptodont, an armored relative of armadillos placed in Glyptodontinae within Chlamyphoridae by 2016 ancient DNA; up to 2 tons, bony carapace, tail club, extinct about 10,000 years ago.

Glyptograptus

Glyptograptus, an extinct biserial planktonic graptolite genus named by Lapworth in 1873, type species Diplograpsus tamariscus Nicholson 1868, ranging from Hirnantian to Telychian worldwide.

Glyptostrobus europaeus

Glyptostrobus europaeus (Taxodium europaeum Brongniart 1833) is a fossil swamp cypress of Neogene Europe, a form species matching extant Glyptostrobus pensilis, known from Miocene Alonnisos, Greece, and widespread European swamp forests.

Glyptostrobus pensilis

Glyptostrobus pensilis (水松, Chinese swamp cypress, Mai Hing Sam) is the sole living species of its genus, a semi-aquatic Cupressaceae conifer of southern China, Laos, and Vietnam, IUCN Critically Endangered with few hundred wild trees, pneumatophores, and a Cretaceous-to-Pleistocene fossil record.

GM 4L60-E transmission

The GM 4L60-E is a four-speed, rear-wheel-drive automatic transmission with overdrive and full electronic control, introduced by General Motors in 1993 and built through 2014.

GM 4L80-E transmission

The GM 4L80-E is a heavy-duty electronically controlled four-speed automatic overdrive transmission introduced by General Motors in 1991 as the overdrive successor to the TH400, used in heavy trucks, vans, and the Hummer H1.
