Patatin-like phospholipase domain-containing protein
Patatin-like phospholipase domain-containing proteins (PNPLAs, pPLAs) are lipid hydrolases defined by a patatin domain from potato tuber, with a Ser-Asp dyad and GXSXG motif; nine human members (PNPLA1–9) act in lipid metabolism and disease, and plant, bacterial, and parasite homologs exist.

Patch-seq
Patch-seq is a laboratory technique that combines whole-cell patch-clamp recording with single-cell RNA sequencing to measure the electrophysiology, morphology, and gene expression of the same individual neuron.
Patch-sequencing
Patch-seq (Patch-sequencing) is a multimodal neuroscience technique combining patch-clamp electrophysiology, single-cell RNA sequencing, and morphology in the same neuron, first implemented reliably in 2016 and central to brain cell type atlases.

Patchwork is the needlework technique of sewing small fabric pieces into a larger flat design, distinct from quilting; also called piecework or pierced work. Known for piecing over paper, crazy patchwork, Gee's Bend quilts, and modern quilting's bold, improvisational style.
Patchy particles
Patchy particles are colloidal particles patterned with a small, fixed number of attractive patches, giving directional bonding and limited valence that control how they self-assemble.
Pâté
Pâté (pâté en croûte, pâté de foie gras) is a cooked, seasoned paste of ground meat, liver, or vegetables served cold; originally a medieval filled pastry pie, now a charcuterie staple with Listeria and Campylobacter safety concerns and a modern revival.

Patel
Patel is a Gujarati surname from the title for village headman (Sanskrit pattakila), carried above all by the Patidar landowning caste of Charotar, Gujarat, formerly called Kanbi, and by many other groups worldwide.
Patella
Patella (kneecap), largest sesamoid bone, embedded in the quadriceps tendon at the knee; increases quadriceps leverage (31% of extension torque at full extension), ossifies at age 5-6, prone to dislocation and fracture.
Patella (gastropod)
Patella (Linnaeus, 1758) is a genus of true limpet gastropods in Patellidae, Patellogastropoda, with about nine species on northeastern Atlantic and Mediterranean rocky shores, distinct from southern-African patellid genera Cymbula, Helcion, and Scutellastra.
Patella vulgata
Patella vulgata, the common limpet, is a northeast Atlantic intertidal patellid gastropod from north Norway to Portugal, a dominant grazer with a homing scar, protandrous sex change, and low-risk alien status in Norway.
Patellar reflex
Patellar reflex (knee jerk, Patellarsehnenreflex): monosynaptic L2-L4 stretch reflex elicited by tapping the patellar tendon, causing quadriceps contraction; described by Erb and Westphal in 1875 and increasingly quantified with EMG and motion analysis.
