1. Lihlopha tse fapaneng

Lintho tsa ho hōla lia hlokahala ho laola kholo e tloaelehileng le metabolism ea likokoana-hloko, empa li ke ke tsa etsoa ka botsona ho tsoa mehloling e bonolo ea carbon le nitrogen.

Li-peptide ke α-amino acid tse hokahaneng hammoho ka litlamo tsa peptide ho etsa metsoako, e leng lihlahisoa tse mahareng tsa proteolysis.

2. Liphello tse fapaneng

Peptide e sebetsang e laola kholo, nts'etsopele, taolo ea 'mele ea ho itšireletsa mafung le metabolism ea' mele oa motho, 'me e maemong a leka-lekaneng' meleng oa motho. Lintho tsa ho hōla ke lintho tse khothalletsang ho hōla ha lisele. Lintho tsa ho hōla li fumanoa li-platelet le liseleng tse fapa-fapaneng tsa batho ba baholo le ba embryonic le liseleng tse ngata tsa setso.

Motsoako o entsoeng ka ho felloa ke metsi 'meleng le condensation ea limolek'hule tse peli tsa amino acid o bitsoa dipeptide,' me ka papiso, tripeptide, tetrapeptide, pentapeptide, joalo-joalo. Li-peptide ke metsoako e atisang ho etsoa ke ho felloa ke metsi 'meleng le condensation ea 10 ~ 100 ea limolek'hule tsa amino acid.
