Q

LDL

A

50% colesterol
transporta colesterol de la ficat la celule

Q

catabolism glicerol

A

in citoplasma
glicerol => DHAP (dihidroxiacetonfosfat -intermediar in glicoliza) => acid piruvic SAU glucoza

Q

catabolism AG

A

in mitocondrie
AG (16) => 8 acetil CoA (2) (prin betaoxidare) => intra in ciclul Krebs => 129 ATP

Q

absorbtia aa din intestin se realizeaza

A

activ/ difuziune facilitata

25

26
dezaminare
gruparea NH2 e inlocuita cu gruparea ceto rezulta NH3 => intra in ciclul ureei/ornitinei +CO2 => ureea - eliminata renal
