--> as. karboksilat + rantai hidrokarbon

bervariasi karena:
panjang rantai
ikatan yang terjadi
konfigurasi cis-trans

mempengaruhi sifat dan kejenuhan isolator panas
cadangan energi (triasil gliserol)
membran sel dan membran-membran sel
jaringan saraf (sel dan serat saraf)
transportasi lipid dalam darah
biosintesis hormon steroid, kalsotriol & asam empedu
biosintesis prostaglandin, prostasiklin tromboxan dan leukotrien Total kolesterol : 200 mg/dL
LDL kolesterol : 130 mg/dL
HDL kolesterol : 35 mg/dL
Trigliserida : 250 mg/dL 4 lipid yang didapat dari makanan:
- monounsaturated fat
-> alpukat
- polyunsaturated fat
-> carnola oil, corn oil, salmon
- saturated fat
-> butter, keju, telur
- trans fat
-> fast food, cookies konsumsi manusia = TAG
dimulai dari rongga mulut dan lambung
terutama di usus halus
melibatkan garam empedu, enz. lipase dan colipase
diserap dalam bentuk monogliserida dan asam lemak.absorbsi membutuhkan enzim lipase
diproduksi oleh pankreas (utama), saliva dan gaster Kelompok 1: lipid?
- klasifikasi
- fungsi
- pencernaan dan absorpsi

cholesterol?
- funsi?
- jumlah yang dibutuhkan?
- sumber?
Lipid senyawa kimia yang larut dalam pelarut non-polar (kloroform dan eter) Kolesterol steroid alkohol (C27H45OH)
terdapat di cairan tubuh dan sel-sel hewan yang meregulasi kelarutan membrane Komponen kolesetrol 1. Hidroksil
2. 4 cincin hidrokarbon
3. Hydrocarbon tail 1. menjaga integritas membran sel
2. prekursor dari asam empedu
3. prekursor dari vitamin D
4. sintesis hormon steroid Kadar Kolesterol Kadar kolesterol darah dipengaruhi oleh:
Diet
Keturunan
Umur
Jenis kelamin Obesitas
Stress
Alkohol
Aktivitas fisik dihasilkan tubuh
produk hewani
- telur, daging, ikan, mentega THANK YOU
